Little Owl part 2

At 16:16 we saw the Little Owl on Streatham Common again, at first the silhouette looked so much like a cartoon owl I assumed it was a branch, but then it moved and swooped down onto the open ground before swooping up into the very high branches of a plain tree,  where he stayed for a few minutes, dogs and noisy children passed beneath the tree not knowing he was there. He then swooped down again and off. It was another very fine night like last night, though perhaps not as cloudless, he was more silhouetted then my Monday sighting, but great to now know some of his (or her) habits and launching posts. I'd like to hear this owl but so far it has been silent, quite a lot of alarm calls nearby from blackbirds, magpies and starlings, but not sure if the Little Owl would cause that, it was probably us, sneakng around in the dusk..

Clearly heard the drilling sound of a woodpecker at lunchtime yesterday while doing Tai Chi in the Rookery, Peter told me this is unusually late for such a call and that it was certainly a Great Spotted.
